Magnetic monopole theory gets stronger

September 5, 2009 Leave a comment Go to comments

“”People have been looking for monopoles in cosmic rays and particle accelerators — even Moon rocks,” says Jonathan Morris, a researcher at the Helmholtz Centre for Materials and Energy in Berlin.

Now Morris and others have found the strongest evidence yet for magnetic monopoles, in small crystals about the size of an ear plug. When the crystals are chilled to near absolute zero, they seem to fill with tiny single points of north and south.

The points are less than a nanometre apart, and cannot be measured directly. Nevertheless, Morris and other physicists believe they are there. They make their case in two papers published today in the journal Science1,2, and other work published on the pre-print server arXiv.org3,4.”
